Throwing a 50th birthday dinner in your backyard is about celebrating a major milestone, not stressing over kitchen prep. A private chef and full catering setup for a good crowd usually comes out to around $2,200. The real trick is timing your bookings so you secure the menu you want without draining your checking account all at once.
You want to lock in your chef at least four weeks out since good cooks fill their weekend calendars fast. Renting extra tables, lights, or glassware can wait a couple of weeks. When the big catering bills drop, spreading out the cost gives you room to breathe.
Keep in mind that a 0% intro APR is a strict deadline, not free money. If you still have a balance on your card when those 15 months end, standard interest rates kick in on the remaining amount, making your dinner party significantly more expensive.
